Java is both a programming language and a computing platform. The former allows you to develop applications and the latter allows you to run the applications that you, or others, develop.

Java was intended to be simple to use, have built-in network support, utilize object-oriented programming methods, and perform functions remotely and securely.

Eclipse is an open-source Integrated Development Environment (IDE) supported by IBM. Eclipse is a popular script creator for Java application development (Java SE and Java EE) and Android apps.
